Title: A UNIFIED TEST ON THE BASIC PROPERTIES OF CONCRETE USING SHRINKAGE REDUCING AGENT
Abstract:This report investigates basic properties, such as compressive strength, drying shrinkage and freeze-thaw resistance, of normal strength concrete containing shrinkage reducing agent (SRA) of three bra...This report investigates basic properties, such as compressive strength, drying shrinkage and freeze-thaw resistance, of normal strength concrete containing shrinkage reducing agent (SRA) of three brands, by same cement and aggregates as well as water-to-cement ratio (=0.5). SRA-added concretes show that compressive strength tend to lower with the increase in dosage, drying shrinkage strain is obviously reduced (more than approximately 15 %), while freeze-thaw resistance is significantly deteriorated.Read More
